[PATCH] intel_th: INTEL_TH should depend on HAS_DMA

From: Geert Uytterhoeven
Date: Mon Nov 09 2015 - 04:36:41 EST

If NO_DMA=y:

ERROR: "dma_free_coherent" [drivers/hwtracing/intel_th/intel_th_msu.ko] undefined!
ERROR: "dma_alloc_coherent" [drivers/hwtracing/intel_th/intel_th_msu.ko] undefined!
ERROR: "dma_supported" [drivers/hwtracing/intel_th/intel_th.ko] undefined!

Add a dependency on HAS_DMA to fix this.
